At a certain temperature, the solubility of aluminum hydroxide is (8.70x10^-13) M. What is the Ksp at this temperature?

Answers

Answer 1

The solubility product (Ksp) at the given temperature is 2.27×10⁻²⁴

How do I determine the solubility product (Ksp)?

We'll begin by writing the dissociation equation of aluminum hydroxide, Al(OH)₃. This is shown below:

Al(OH)₃(aq) <==> Al³⁺(aq) + 3OH⁻(aq)

Finally, we shall determine the solubility product (Ksp). This is illustarted below:

Concentration of Al(OH)₃ = 8.70×10⁻¹³ MConcentration of Al³⁺ = 8.70×10⁻¹³ MConcentration of OH⁻ = 3 × 8.70×10⁻¹³ = 2.61×10⁻¹² MSolubility product (Ksp) =?

Ksp = [Al³⁺] × [OH⁻]

Ksp = 8.70×10⁻¹³ × 2.61×10⁻¹²

Ksp = 2.27×10⁻²⁴

Thus, we can coonclude that the solubility product (Ksp) is 2.27×10⁻²⁴

How many moles are in a system that is 223 K, with an internal pressure
of 10 atm, in a fixed container that is 27 L
O 14.75 mol
O 1.21 mol
O 825 mol
5.42 mol
* 2 points

Answers

Answer:

A.) 14.75 mol

Explanation:

To find the amount of moles, you need to use the Ideal Gas Law equation:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = number of moles

-----> R = Ideal Gas Constant (0.08206 L*atm/K*mol)

-----> T = temperature (K)

You can plug the given values and the constant into the equation and simplify to find "n".

P = 10 atm                    R = 0.08206 L*atm/K*mol

V = 27 L                       T = 223 K

n = ? moles

PV = nRT                                                                   <----- Ideal Gas Law

(10 atm)(27 L) = n(0.08206 L*atm/K*mol)(223 K)   <----- Insert variables

270 atm*L = n(18.299 L*atm/mol)                           <----- Mutliply

14.75 mol = n                                               <----- Divide both sides by 18.299

Answer:

A

Explanation:

Independent variable: the surface of the slope rug, bubble wrap and wood

For this experiment, various solutions were compared to look for precipitation or bubbling. The precipitates or bubbles are the independent variable in the experiment. Therefore, option B is correct.

What is precipitation ?

The term precipitation is defined as a solid produced by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid.

A substance separated from a solution or suspension by chemical or physical change, usually as an insoluble amorphous or crystalline solid.

A compound may precipitate when its concentration exceeds its solubility. This can be caused by temperature changes, solvent evaporation, or solvent mixing. A strongly supersaturated solution precipitates more quickly.

Independent variable are the surface of the slope rug, bubble wrap and wood.

What mass of iron starting at 100.0 oC must be added to 50.0 g of water at 25.0 oC to increase the water’s temperature to 65.0 oC? Iron’s specific heat capacity is 0.450 J/(g oC).

Answers

The mass of the iron at 100°C is equal to 531.3 grams.

What is the specific heat capacity?

The specific heat capacity can be defined as the quantity of heat required to raise the temperature by one-degree Celcius in one unit of substance.

The energy is lost or absorbed will change the temperature of the substance, which can be shown as:

Q = mCΔT

Given, the initial temperature of the iron = 100°C

The initial temperature of water = 25 °C

The final temperature of both iron and water = 65°C

The specific heat capacity of the iron, C = 0.450 J/g°C

Water's specific heat capacity, C = 4.184 J/g°C

Heat lost by Iron (Fe) = Heat absorbed by water

- m × (0.450 J/g°C) × (65 - 100)°C =  50 × (4.184 J/g°C) × (65 - 25)°C

15.75 m = 8368

How do I determine the temperature change?

From calorimetry, we understood that heat released or lost is given by:

Where

Q is heatM is the mass C is the specific heat capacityΔT is the temperature change

With the above formula, we can determine the temperature change of the silver. This is illustrated below

Q = MCΔT

-982 = 5 × 0.237 × ΔT

-982 = 1.185 × ΔT

The mass in grams of sulfuric acid, H₂SO₄, that will be produced by the complete reaction of 40.01 grams of sulfur trioxide is 49.01 grams

How do I determine the mass of sulfuric acid produced?

We'll begin by obtaining the reacting mass from the balanced equation. This is shown below

SO₃(g) + H₂O(l) → H₂SO₄

Molar mass of SO₃ = 32 + (16 × 3) = 80 g/molMass of SO₃ from the balanced equation = 1 × 80 = 80 gMolar mass of H₂SO₄ = (1 × 2) + 32 + (16 × 4) = 98 g/mol Mass of H₂SO₄ from the balanced equation = 1 × 98 = 98 g

From the balanced equation above,

80 g of SO₃ reacted to produce 98 g of H₂SO₄

Finally, we shall determine the mass of sulfuric acid, H₂SO₄ produced as illustrated below:

From the balanced equation above,

80 g of SO₃ reacted to produce 98 g of H₂SO₄

Therefore,

40.01 g of SO₃ will react to produce = (40.01 × 98) / 80 = 49.01 g of H₂SO₄
